Yes, that is correct.
Kinetic Energy.
Not all potential energy is converted to kinetic energy in a roller coaster because some of the potential energy is lost due to friction, air resistance, and other forms of energy dissipation. This loss of energy results in not all of the potential energy being transformed into kinetic energy.
Friction causes kinetic energy to be converted into heat energy.
At the start of a swing the pendulum has lots of potential energy but no kinetic energy. As it moves downwards the potential energy is converted into kinetic energy. In the upswing the kinetic energy is converted back into potential energy. Some of the energy is converted into heat by friction which is why the pendulum slows down.
When potential energy is converted into kinetic energy, it is transformed into the energy of motion.
In a swing, the potential energy is converted to kinetic energy as the swing moves downwards. At the highest point of the swing, all the potential energy is converted to kinetic energy, and as the swing rises back up, the kinetic energy is converted back to potential energy. Friction and air resistance also play a role in converting some of the energy into heat.
Kinetic energy is the energy in a mass of matter that is in motion, the energy of motion. Potential energy (where mass is in a gravity field) can be converted into kinetic energy Chemical energy (of an explosion) can be converted into kinetic energy Electrical energy can be converted into kinetic energy (eg in an electric motor)
When you give your dog energy bites it keeps he/she stronger and with a better heart.

If potential energy is not converted into kinetic energy (or into any other type of energy) then it remains potential. Potential energy does not expire.
It CAN be converted to kinetic energy, but it won't always do so.
When a parachute is deployed, the potential energy of the object is converted into kinetic energy as it falls. As the parachute opens and increases air resistance, this kinetic energy is then converted into thermal energy due to air friction and potential energy as the object slows down and descends gently.
